[o all whom, it may concern:

Be it known that I, WILLIAM A. SEnvnRs, a citizen of the United States,residing at Oskaloosa, in the county of Mahaska and State of Iowa, haveinvented a new and useful Steam or Hot-Tater Radiator, of which thefollowing is a specication.

This invention Irelates to steam and hotwater radiators; and it has forits object to provide an improved radiator' of this character adaptedfor use in connection with a onepiperadiator system and so constructedas to require less attention, while at the same time providing for quickand uniform heating and a ready adaptation to either hotwa ter or steamheating without changing any pipe connections.

With these and manyother objects in view, which will readily appear asthe nature of the invention is better understood, the same consists inthe novel construction, combination, and arrangement of partshereinafter more fully described, illustrated, and claimed.

In the drawings, Figure 1 is a side elevation of a steam and hot-waterradiator embodying the present invention. Fig. 2 is an endview thereof.Fig. 3 is a vertical longitudinal sectional View on the line 3 3 of Fig.2. Fig. 4 is a vertical sectional view on the line 4 4 of Fig. 3. Fig. 5is an enlarged detail horizontal sectional view on the line 5 5 of Fig.3.

Referring to the accompanying drawings, l designates a radiatoressentially comprising a series of upright hollow radiator-sections 2,arranged side by side in the usual manner in which radiator-sections areset up for use, and each of these adjacent radiatorsections consists ofan upright looped casting having opposite tubular columns or legs 3,communicating with each other through the interior hollow spaces 4 atthe top and bottom of the section, this construction being substantiallysimilar to the construction of ordinary hollow radiator-sections. The series of upright radiator-sections 2 comprising the radiator are providedin their adjacent communicating sides and near their upper and lowerends with the alined circulating-passages 5, which receive therein theusual coupling-nipples 6 for connecting the sections of the radiatortogether, while at the same time providing communication between all ofthe sections at the top and bottom.

In the present invention the alined circulating-passages 5 at the bottomof the radiator are of a sufficiently large diameter to receive thereina continuous horizontal steam pipe 7, which extends within the bottom ofthe radiator from one end section tothe other. The pipe 7 issufiiciently smaller than the alined passages 5, through which itextends, to allow a perfectly free circulation of water within theradiator around the pipe '7, and one of the threaded ends 8 of saidhorizontal continuous steam-pipe 7 is threaded in the pipe-opening 9,formed in one side of the partition-boxing 10, cast integrally withinthe lower end of one of the end sections 2 of the radiator. The said endsection 2 of the radiator having the partition-boxing 10 is provided atone side, near its lower end, with an enlarged drain-chamber 1l, offsetfrom the side of the boxing 10 opposite the side in which the pipe 7 isfitted, and this opposite side of the partition-boxing l0 is providedwith a drain-opening 12, that is adapted to be covered and uncovered bya drain-valve 13, workin g within the chamber 11 and fitted on the innerend of a valvestem 14, working through the stuffing-box 15, itted on theouter side of the chamber 11, and carrying at its outer end a hand-knob1G, which is manipulated with the hand to open and close the valve 13.

The partition-boxing 10, within one of the end sections 2 of theradiator, separates the opposite tubular columns or legs of this sectionof the .radiator at their lower ends, and these opposite tubular columnsor legs of said end section of the radiator are designated,respectively, 3"l and 3b, the tubular column or leg 3a communicating atits lower end with the interior of the boxing 10 and the pipe 7 and thelower end of the column or leg 3b communicating with the drain-chamber11 and the space exterior to the boxing l0, as clearly illustrated inFig. 5 of the drawings.

The threaded end 8 of the pipe 7, opposite the end section having theboxing l0, is extended through a pipe-openin g 17in one lower side ofthe opposite end section and has detachably threaded thereon abushing-cap 18. The bushing-cap 18 is provided with aneccentrically-disposed opening 19, in which is fitted one end of thesteam-supply pipe 20, having a suitable cut-off valve 2l. The endsection 2, of the radiator opposite the section having the separatedcolumns or legs 3a and 3b, is provided at one side and near its upperend, preferably, with a suitably-constructed self closing vent valve 22,which when pressed will vent the radiator of air veryquickly, but whichwill close itself when released, so as to prevent any leak in case ofthe water filling the radiator should it be forgotten to close the ventwhen fillin g the boiler.

In the operation of the radiator by closing the drain-valve 13 andopening the air-vent valve 22 the steam passes directly throughthesteam-pipe '7 into the tubular column or leg 3 of the end section 2opposite the steamsupply pipe 20, and passing upward through thecolumn-or leg 3 spreads itself throughout all the sections 2, so as toentirely fill the radiator with steam. The steam continues to condenseand lill all of the communicating sections of the radiator with water ofcondensation up to the water-line of the radiator, which is at the lowerside of the alined circulating-passages 5 within the top of theradiator. Then the water of condensation reaches the water-line near thetop of the radiator, the same iinds escape into the column or leg 3 ofthe end section receiving the steam and returns downward through saidcolumn or leg 3" into the pipe 7, and thence through the supply-pipe 20back to the boiler from which such pipe leads. The continuedcondensation of the steam maintains the radiator nearly full of hotwater and always at the same level, as the overflow-water passes backinto the boiler through the course described, and at this point it is tobe observed that all of the radiator-sections communicate with eachother at the bottom, so as to keep the pipe 7 entirely surrounded by hotwater, whereby the steam in said pipe is radiated to the water and keepsthe same at about boiling temperature. By reason of this operation theradiator is very eflicient for hot-water heating, but by opening thedrain-valve 13 the standing water in the radiator drains through theopening 12 into the pipe 7 and returns to the boiler through t-he pipe20, communicating with one end of the pipe 7. By thus draining theradiator of water the same can be used as an ordinary steam-radiator inthe same manner as radiators used in connection with one-pipesteam-heating systems. The eccentricity of the pipe-opening 19 of thebushing-cap disposes the end of the pipe 2O therein sufficiently nearthe lower side of the pipe 7 to receive all the water drained back intothe boiler through said pipe, as will be readily understood by thoseskilled in the art.

The construction of radiator herein described provides for a thoroughheating of the hot water within the radiator, especially for the reasonthat the ysteam passes through the water within the base or bottom ofthe radiator and exhausts at the top of the water, thereby heating thewater both at the top and the bottom, and the arrangement also providesfor reducing the steam-heating surface to a minimum and radiating theheat principally from the Water, and the drainvalve is not onlyimportant in converting the radiator from hot-water to steam heating,but also allows the water to be drained out to prevent freezing.

Changes in the form, proportion, and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention.

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is-

1. A radiator comprising a series of upright hollow sections formed withopposite tubular columns or legs communicating with each other at thetop and bottom, one of the end sections of the radiator being providedwithin its lower end with a partition separating the opposite tubularcolumns or legs of the section at their lower ends, and a horizontalsteam-pipe extending continuously through all sections of the radiatorat the bottom and itted at one end in said partition so as tocommunicate with one of the tubular columns or legs of said end section,substantially as set forth.

2. A radiator comprising a series of upright hollow sections formed withopposite tubular columns or legs communicating with each other at thetop and bottom, one of the end sections being provided within its lowerend with a partition-boxing separating the opposite tubular columns, andat one side of said boxing with an offset drainchamber, said boxingbeing provided in one side with a pipeopenin g and in the directlyopposite side with a drain-opening, a suitably-operated drainvalveworking within said drain-chamber and adapted to cover and uncover saiddrain-opening, a steam-pipe extending continuously through the interiorlower portion of the radiator and fitted at one end in said pipe-openingof the partition-boxing, a valved supplypipe connection with the otherend of said steam-pipe, and an air-vent valve iitted to one of the endsections of the radiator near the top, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
